Whoops: dragged along an extra copy of the protocol
definition file by mistake. This isn't needed so long as the one in include/rpcsvc is installed.

/*
|
||||
* This protocol definition file describes a file transfer
|
||||
* system used to very quickly move NIS maps from one host to
|
||||
* another. This is similar to what Sun does with their ypxfrd
|
||||
* protocol, but it must be stressed that this protocol is _NOT_
|
||||
* compatible with Sun's. There are a couple of reasons for this:
|
||||
*
|
||||
* 1) Sun's protocol is proprietary. The protocol definition is
|
||||
* not freely available in any of the SunRPC source distributions,
|
||||
* even though the NIS v2 protocol is.
|
||||
*
|
||||
* 2) The idea here is to transfer entire raw files rather than
|
||||
* sending just the records. Sun uses ndbm for its NIS map files,
|
||||
* while FreeBSD uses Berkeley DB. Both are hash databases, but the
|
||||
* formats are incompatible, making it impossible for them to
|
||||
* use each others' files. Even if FreeBSD adopted ndbm for its
|
||||
* database format, FreeBSD/i386 is a little-endian OS and
|
||||
* SunOS/SPARC is big-endian; ndbm is byte-order sensitive and
|
||||
* not very smart about it, which means an attempt to read a
|
||||
* database on a little-endian box that was created on a big-endian
|
||||
* box (or vice-versa) can cause the ndbm code to eat itself.
|
||||
* Luckily, Berkeley DB is able to deal with this situation in
|
||||
* a more graceful manner.
|
||||
*
|
||||
* While the protocol is incompatible, the idea is the same: we just open
|
||||
* up a TCP pipe to the client and transfer the raw map database
|
||||
* from the master server to the slave. This is many times faster than
|
||||
* the standard yppush/ypxfr transfer method since it saves us from
|
||||
* having to recreate the map databases via the DB library each time.
|
||||
* For example: creating a passwd database with 30,000 entries with yp_mkdb
|
||||
* can take a couple of minutes, but to just copy the file takes only a few
|
||||
* seconds.
